The HR 2mm Eyepiece is designed for observation of subtle differences of the surface of the planets. The high resolution eyepiece deliver breathtaking, superb images with extremely high level of definition and contrast.
The resolving power outperforms similar eyepieces designed for planetary viewing. The HR-series maintains more than a 97% Strehl ratio to the edge of the field of view when combined with a Vixen AX103S refractor. In comparison, the ratio is about 90% with the use of a standard LV2.5mm eyepiece.
The HR-series work extremely well with the Vixen R200SS as it has the ability to correct coma aberration. Even at the edge of the field of view, the HR-series have a 93% Strehl ratio. In comparison the Strehl ratio with use of the LV2.5mm falls rapidly as the viewing object is moved toward the edge of the field of view.
The ratio is only 93% at a fifth from the center and 0% at the edge. Conventional eyepiece specifications merely show the performance when an object is put in the center of the field of view of the eyepiece. As a result, the resolving power declines as you move toward the edge of the field of view. The HR-series are best suited for observing the surface of the moon to extend your view to the entire field of view.
While most eyepieces are constructed from 7 or 8 lens elements, the Vixen HR-series are constructed with a 5 lens elements design to achieve the largest possible transmission of light. The absorption and reflection of light are virtually eliminated.
The Vixen AS-coating achieves extremely high light transmission of 99.9% per lens surface. It is applied to each of the surfaces to deliver extremely high contrast images.
The grooved lens frame construction contributes to the reduction of stray light. The inside of the eyepiece is perfectly threaded and blackened to prevent deterioration of the image from stray light. The inner baffle rings effectively stop any stray light. Even a hint of reflection which might occur on the tip of the sleeve is eliminated.
